Generally, NMs are categorized according to their dimensionality, morphology, state, and chemical composition (Gleiter, 2000).This classification also depends on their size, which ranges from 1-100 nm in at least one dimension (see Fig. 2). The intracellular method consists of transporting ions into the microbial cell to form nanoparticles in the presence of enzymes. Nanoparticle drug delivery systems with relation to other scales CLASSIFICATION OF NANOPARTICLES There are various approaches for classification of nanomaterials. According to their dimensionality, nanomaterials include nanoparticles, nanotubes, and nanofilms. Each type of allotropic modification is characterized by appropriate sp-bonding structure . Nanoparticle dimensions between 1 nm and 1000 nm Nano derives from the Greek word "nanos", which means dwarf or extremely small. We classify nanoparticles to be particles less than 100nm in diameter that exhibit new or enhanced size-dependent properties compared with larger particles of the same material.

Hydroxyapatite [Ca 10 (PO 4) 6 (OH) 2] is an important component in human bodies, especially in bones and teeth, as the main mineral.Due to the excellent adsorbability with many compounds, Hap nanoparticles have already been extensively used in the formation of Pickering emulsions, which can be applied to a variety of applications such as biomaterials, adsorbents, and catalysts. The classification of nanomaterials mainly depends on the morphology and their structure, they are classified into two major groups as Consolidated materials and Nanodispersions. Besides the assessment of health effects of nanoparticles, the classification of nanoparticles is becoming more important in the manufacturing of various semiconductor devices from nanoparticles through CVD processes because the inclusion of large particles in deposited film may deteriorate the performance (Kruis et al., 1998). The chapter discusses classification of dispersive systems according to their aggregation states, size, and dimension. Classification of nanoparticles There are various approaches for classification of nanomaterials. From the classification, it is evident that the behavior of these particles is purely based on shapes, sizes, morphologies, and dimensions. Amongst the types of automobile exhaust, diesel engines release 20-130 nm sized particles whereas gasoline engines release 20-60 nm sized particles [ 89 - 90 ]. Nanomaterials can be made of single elements, such as metals or carbon, or multiple elements, such as metal oxides or . Definition of Nano Particles: Nanomaterials or the Nanoparticles are the set of particles or the substances where atlas one dimension is less than approximately 100nm. The DMA has been improved to operate at pressures of less than 10 Torr. synthesis mainly by physical, chemical, mechanical, and biological methods. In this study, ML algorithms are used to learn atoms types over structural geometrical data of anatase TiO2 nanoparticles produced at different temperature levels with the density-functional tight-binding method (DFTB). Nanoparticles (NPs; 1-100 nm in size) have a special place in nanoscience and nanotechnology, not only because of their particular properties resulting from their reduced dimensions, but also because they are promising building blocks for more complex nanostructures. nanoparticles are now used in every objects like from cooking vessel, electronics to renewable energy and aerospace industry. Liposomes, sphere-shaped vesicles consisting of one or more phospholipid bilayers, were first described in the mid-60s. The drug is dissolved, entrapped, encapsulated or attached to a nanoparticle matrix. Specifically, nanoparticles (NPs) can be designed to obtain nanodevices for drug delivery, imaging and/or diagnosis in medicine. nanoparticles are less efficiently removed than larger particles by the macrophage clearance mechanisms in the lungs, causing lung damage, and that nanoparticles can translocate through the circulatory, lymphatic, and nervous systems to many tissues and organs, including the brain. days.

The present work confirmed that the filter employed in the present work can separate particles smaller than 100 nm. The aim of this study was to synthesize, characterize and evaluate the antimicrobial activity of the CNPs. Nanoparticles are defined as particulate dispersions or solid particles with a size in the range of 10-1000nm. With increase in temperature there will be decrease in particle size. or it can be also classically illustrated as the follows: Nanomaterial is an object that has atleast one dimension in the nanometer scale approximately 1-100nm.
